Fit Test Hood by PowerPak protects workers during the conductive qualitative fit test. The reusable hood is an inherent part of periodic fit tests that help to evaluate a respirator's performance or efficiency. It is fabricated from durable poly-coated material. The protective hood has a large viewing window made of optically clear PET material that provides full visibility and ease of reading the test page. It has a string closure type that enables the wearer to adjust the fitting of the hood. The respirator testing hood is great for claustrophobic users as the large viewing window provides 360-degree visibility.
